The present invention relates to a resealable container comprising: a polyethylene terephthalate-based container body comprising a bottom side and at least one upwardly extending sidewall, wherein the sidewall terminates in an open end of the container; a flexible film sealed to the container body, over the open end of the container, wherein the flexible film comprises: a polyethylene-based first film layer; a pressure sensitive adhesive layer adjacent a lower surface of the first film layer; a polyolefin plastomer skin layer adjacent a lower surface of the pressure sensitive adhesive layer, wherein the first layer, pressure sensitive adhesive layer, and skin layer are coextruded; and a heat seal layer printed onto a lower surface of the skin layer and heat sealed to the container body.

A package includes a container and a closure. The container includes a body formed to include a product-storage region adapted to store products therein and a brim coupled to the body and formed to include a mouth opening into the product-storage region. The closure is coupled to the brim of the container by melting a portion of the closure together with a portion of the brim to block access to the products stored in the product-storage region.

An extensible bearing element of a tool for sealing a bottom or a lid of a cardboard package on a body of said package has a generally polygonal shape and a cross-sectional profile. The bearing element is formed by two parallel extension sections extending along an extension direction, each connected, at one of their ends, to a bearing section. The extension sections and the bearing section define an inflation cavity. The extension sections are configured to extend along the extension direction when the bearing element is inflated. The bearing section comprises a substantially flat, free bearing surface that contacts the package body. The bearing surface extends along a plane substantially normal to the extension direction. The bearing section further comprises, at the junctions with the extension sections, beveled release portions. An inflation device comprising such an extensible bearing element is also described.

The invention comprises an ovenable packaging structure having an integral one-way valve. The laminate structure comprises an outer layer having a cut line which defines a flap that is separable from the outer layer, wherein the outer layer is adhered to an inner layer having a cut line which is offset from the outer cut line and defines a portion that is separable from the inner layer along the inner cut line and defines an opening into the packaging structure. The adhesive between the layers comprises, in an embodiment, a channel of pressure sensitive adhesive which surrounds both the outer cut line and the inner cut line, wherein the channel of pressure sensitive adhesive defines the perimeter of at least one adhesive-free valve chamber within said channel. The valve chamber comprises at least a portion of the outer cut line and the inner cut line.

Containers are described that allow a consumer to see inside the container and to more easily access the products. One form of the container includes a base member with a lid defining a window. A flexible laminate with a peelable flap portion is attached to the lid to provide access to the products inside. The flexible laminate includes a first film layer laminated to a second film layer. The first film layer includes a first cut line defining a peelable flap portion and the second film layer includes a second cut line offset from the first cut line that defines an opening into the container. First and second reclose surfaces defined between the cut lines on the corresponding film layers include pressure-sensitive adhesive to allow the container to be re-sealed via movement of the peelable flap portion back into engagement with the flexible laminate remaining with the container.

The present disclosure relates to a two-side adherable high-frequency induction heating container sealing member, the sealing member comprising: an upper layer that comprises a first thermal-adhesion sealing layer, a first aluminum foil layer, an intermediate base layer, a synthetic resin layer having tensile strength and hardness, and a first thermal-adhesion resin layer, which are successively formed from the top to the bottom, the upper layer having a preformed opening guide cut line-provided opening tab, a preformed opening guide cut strip, and a preformed thermal-adhesion sealing strip; and a lower layer that is formed beneath the upper layer and comprises a second aluminum foil layer and a second thermal-adhesion sealing layer, which are successively formed from the top to the bottom, wherein the first thermal-adhesion resin layer of the upper layer is integrated with the second aluminum foil layer of the lower layer through thermal adhesion.

Improved packages and methods for constructing packages are provided that reduce or prevent leakage into or out of the package. In particular, the package includes a base member and a lidding member with a reinforced perimeter portion that blocks channels that may form at the interface between the base member and the lidding member from extending to the edge of the base member, such that, e.g., liquids have no path to the package exterior. The perimeter portion may be a thicker region of a first film of the lidding member (e.g., a polyethylene emulsion), or the perimeter portion may be formed using permanent adhesive. Frangible layers and/or cut lines may be defined in the material of the base member or the lidding member to allow a controlled break to occur when the lidding member is peeled away from the base member to provide access to the package contents.

A packaging device incorporating a breathable peel/reseal film and enabling a preservation process for allowing for the distribution, storage and multiple servings of a food product, particularly perishable food product(s), and initiating and controlling the transmission rates, respiration rates or deterioration of the perishable food product(s) and thereby, maintaining good internal and external food quality and normal development of flavor and aroma characteristics. The packaging device includes a plurality of atmospheric control attributes that modulates or controls the atmosphere within the packaging device as the food product(s) respire in order to promote the extended shelf-life of the food product and the maintenance of the quality and desirable marketable characteristics of the food product. The atmospheric control attributes can include perforations that may be positioned in breathable peel/reseal film portion of the package to allow the product respiration for multiple servings without substantially altering the shelf life extension properties of the packaging device.

A resealable closure for a container or package in which package integrity is indicated by a structure which breaks and/or produces an audible sound when the resealable closure is opened for a first time. The package integrity feature, in one form includes at least one strip or frangible structure that is initially affixed to two portions which comprise the resealable closure so that upon opening the resealable closure for a first time, at least one of the strips breaks. The strips may include a weakened portion such as a narrowing. Integrity of the package is indicated by an intact strip viewable upon opening the resealable closure and conversely, a broken or non-intact strip would indicate that the resealable closure has been previously opened. Package integrity may also be shown by a moveable second panel or moveable die cut tab portions.

The present disclosure, in one embodiment, relates to a packaging assembly for holding liquids, viscous material, or particulate material. The packaging assembly includes a carton having side and bottom walls and an open top. A self-supporting plastic liner fits inside of the carton and is for containing liquids, viscous material, or particulate material. The liner has a side wall, a closed bottom end, and an open top end having an outwardly-projecting rim. The rim has a radially-extending flange portion, and a dependent skirt portion. When the self-supporting plastic liner is inside of the carton, the dependent skirt portion of the rim hangs over the side walls of the carton. A lidding material is removeably affixed to the rim of the plastic liner. A carton lid closes off the open top of the carton.
